Arrangement for choosing transceiver nodes in a mobile telecommunications network

摘要

A mobile telecommunications network includes a mobile telecommunications device UE , a plurality of transceiver nodes , and control means operable to choose at least one of the transceiver nodes for use by the mobile telecommunications device for uplink communications and to choose at least one of the transceiver nodes for use by the mobile telecommunications device for downlink communications. The uplink and downlink nodes may be different i.e. an uncoupled network. The control means is operable to choose the at least one of the transceiver nodes for use by the mobile telecommunications device for uplink communications based upon at least one criterion that is independent of received signal power/path loss at the UE, such as: the number of the transceiver node antennas; the antenna gain of the or each of the transceiver node antennas; the maximum uplink transmit power allowed by the transceiver node from the mobile telecommunications device: the load of the transceiver node; the backhaul capacity of the transceiver node; and/or the interference level in the uplink to the transceiver node from the UE. An additional method of selecting a transceiver using transceiver characteristics and the received signal power is also disclosed. An arrangement for reducing interference in situations where mobile telecommunications devices engage in Device-to-Device (D2D) communication is also disclosed
